ABSTRACT Background: Conventional dentoalveolar osseous reconstruction often involves the use of graft materials with or without barrier membranes.
Objective: To evaluate the efficacy of bone induction by bone matrix gelatin (BMG), delivered on an absorbable collagen sponge (ACS), compared to a placebo (ACS alone) in human alveolar socket defects.
Methods: 20 alveolar sockets from 10 healthy adults were studied. In all cases, both the mandibular premolar area and the contralateral premolar area (as the control site) were involved. In each of the 10 patients, the extraction sites were filled randomly with BMG and ACS. The repair response was examined on day 90. Qualitative histological and quantitative histometric analysis, including the percentage of newformed bone fill and density were done. Results: Assessment of the alveolar bone indicated that patients treated with BMG had significantly (p
